Data Logging and Testing

The company was one of the first to manufacture Engineering Laboratory Teaching Equipment linked to a personal computer and in order to achieve this, designed and manufactured its own multi-channel data logger. These have proven to be reliable, durable and as a result have already found application within Universities and industrial testing applications worldwide.

Now up dated, and with Windows compatible software, the proven design philosophy has remained. Our data logger systems still offer the lowest cost per channel of any of the well-known stand-alone data loggers currently on the market. The built in transducer power supplies, control features and on board conversion to engineering units avoid many of the hardware and software problems that can occur with plug-in PC cards. The on board memory and data storage make the unit particularly suitable for use with older PC’s which are often transferred for use in workshops and laboratories.

The data logging products are now complemented by a range of industrial test equipment under the HEATT product range that has been specified in a number of international projects relating to phase out of ozone depleting substances.

Due to the individual nature of many applications, detailed specification of transducers is necessary. Please ask for a standard enquiry form from your local representative.


	D102 Data Logger System A 43-channel analogue and digital computer interface with Windows compatible menu driven software for data logging and control of Engineering Laboratory Teaching and Research Equipment. The software allows transducers to be easily and quickly configured to return data in the engineering units selected by the operator and for these configurations to be simply stored using a standard Windows format. The software includes a number of numerical and graphic display options and data files are easily exported to Excel or another spreadsheet format for report writing. Comprehensive instruction manuals are supplied suitable for student operation of the hardware and software.


	Specifically designed transducers can be supplied to measure: pressure, temperature, flow rate, force, displacement, humidity, power, current, voltage, rotational speed and heat flow for most fluids and applications utilising the onboard power supplies ( ±5v, ±15v and +12v) The interface has a simple and logical command format and a separate additional manual is available for those users who wish to write software for specialised control and instrumentation applications. A total of three Data Loggers may be connected to a single computer. For specialised applications calibration to traceable international standards is available.
